C'est une d\u00e9cision d'architecture qui rel\u00e8ve du DSI et du RSSI, mais dont les cons\u00e9quences en cas d'incident, r\u00e9putationnelles, r\u00e9glementaires et financi\u00e8res, remontent directement au dirigeant.<\/p><p style=\"font-weight: 400;\">Le CERT-FR l'a formul\u00e9 dans son bulletin CERTFR-2026-ACT-016 du 13 avril 2026 : les agents doivent \u00eatre d\u00e9ploy\u00e9s dans des environnements isol\u00e9s, avec des r\u00e8gles d'autorisation explicites et une validation humaine obligatoire d\u00e8s qu'une action \u00e0 effet de bord est envisag\u00e9e.
